I don't think buyers of these SSDs want to return it. The only reason to buy such an SSD is to resell it. Effectively they are enabling other scammers.

You can certainly return an item if the title of the listing was inaccurate.

In my experience, eBay won't "flag" dishonest sellers of counterfeit storage products, anyhow. I tried to get a listing selling counterfeit Samsung micro SD drives taken down, but eBay did nothing. I was refunded, but the unsuspecting will continue to be duped.
